| Description: | Integrated Pest Management is a key plan in conservation agriculture to pest control that joins chemical and biological methods to protect crop ecosystem and surrounding natural resources (water, soil, air). Coleoptera order is an important entomological problem in commercial crops causing important losses at least up 15%. Several management strategies are used in their control such as cultural techniques, natural enemies, entomopathogens and chemical agents. Bacillus thuringiensis (Bt) is an entomopathogenic bacteria used widely in pest insect control of Lepidoptera, Coleoptera and Diptera orders. The most important virulence factor of Bt are Cry proteins. Several Cry proteins have lethal activity against coleopteran insects such as Cry1B, Cry1I, Cry3, Cry7, Cry8, Cry9, Cry14, Cry22, Cry23, Cry34, Cry35, Cry36, Cry37, Cry43 y Cry55. It has been found that Bt israelensis-like strains are active against coleopterans. In this review we show the most important determinants with relationship to biological activity of Bt against coleopteran-pests El Manejo Integrado de Plagas es un plan fundamental en la agricultura de conservación que armoniza los métodos químicos y biológicos afín de proteger los ecosistemas agrícolas y sus recursos naturales (agua, suelo, aire). El orden Coleóptera es uno de los problemas entomológicos más importante en los cultivos comerciales causando pérdidas de hasta 15%. Se utilizan estrategias de control de insectos tales como técnicas culturales, enemigos naturales, entomopatógenos y agentes químicos. Bacillus thuringiensis (Bt) es una bacteria entomopatógena ampliamente utilizada en el control de insectosplaga de los ordenes Lepidóptera, Coleóptera y Díptera. El factor de virulencia de Bt más importante son las proteínas Cry. Varias proteínas Cry tienen actividad letal contra los insectos coleópteros como Cry1B, Cry1I, Cry3, Cry7, Cry8, Cry9, Cry14, Cry22, Cry23, Cry34, Cry35, Cry36, Cry37, Cry43 y Cry55. Se ha encontrado que cepas de Bt tipo israelensis son activas contra coleópteros. En esta revisión nosotros presentamos los principales ítems relacionados con la actividad biológica de Bt sobre coleópteros-plaga. |
